1c80503938 fix #H4146 - more enlightenment vs drain resistance
Duplicate of another recent report as far as drain resistance from
Excalibur/Stormbringer/Staff of Aesculapius not being shown by
enlightenment goes, but this one mentioned that it also wasn't being
shown for lycanthropy.  Being inflicted by that does confers level-
drain resistance.  were_change() wasn't calling set_uasmon() since
it isn't changing youmonst.data, but set_uasmon() is were intrinsics
conferred by creature form are set up.  So call it when changing
were-form.  Direct access to u.ulycn wasn't calling it either, so add
a new routine to assign the value to that instead doing so directly.

192372a9ac "fix" #H4040 - energy vortex power drain
Reporter thought the fact that two different DREN cases had different
chances to inflict energy drain was an inconsistency, but it was
intentional.  Attack for DREN damage has 25% chance to drain energy,
and is never used since no monster has such an attack.  Engulf for
DREN damage has 75% chance to drain energy; energy vortices have this,
and the higher chance to be drained while engulfed was intentional.
So add comments explicitly spelling out the 25% and 75% chances.

During beta testing there was a complaint that the energy drain was
much too severe:  once hero's current energy drops to 0, excess drain
for current attack and future drains come out of max-energy instead.
That's survivable for caster-type characters with really high energy,
but drained low energy characters to 0 max energy very quickly.
I agreed with the complaint but didn't implement a fix until too late
for 3.6.0.  I've since thrown that one out and done this one instead.
Change base drain amount from 4d6 to 2d6, and weaken it more to 1d6
when energy is low or strengthen it to 3d6 when energy is high.  It
almost certainly will need further tuning.

    fix #H4066 - bug eating ring of protection

    Intrinsic protection of 0 (usually from having a gremlin steal divine
    protection, but also possible by eating a +0 ring of protection) does
    not contribute to "magic cancellation", the defense attribute that
    makes some special attacks fail.  That's intended.  Negative intrinsic
    protection (not possible from having divine protection, but turns out
    to be possible from eating negatively enchanted/charged rings of
    protection), did contribute.  That wasn't intended, so stop it.
    (Positive intrinsic protection gives a magic cancellation of 1 if worn
    armor doesn't provide any MC.)

a2f15cfd61 theft vs donning, round 2 (trunk only)
The message "you stop taking off <that armor>" when interrupted by a
nymph's or monkey's theft attack would only be given if you were using 'A'
to take off the armor.  If you used 'T', you'd get "you stop putting on
<that armor>" instead.  The fix for that also makes it easy to vary the
nymph message "<the nymph persuades> you to start taking off" to be "<the
nymph persuades you to continue taking off" when taking that same piece
of armor off was interrupted by the theft.

ef888e065a fix #H2589 - theft vs donning/doffing (trunk only)
From a bug report, having some
armor stolen while in the midst of putting on armor--when both items have
a multiple turn completion delay--could result in side-effects for the
latter item being reversed even though they hadn't been applied yet.  So
you'd lose points of Int and Wis when attempting to put on a positively
enchanted helm of brilliance, or gain such with a negatively enchanted one.

     steal() was assigning to afternmv before it had been used to finish the
action of putting on or taking off armor.  Fix by interrupting the attempt
to put on or take off armor when being victimized by theft (or being hit by
succubus or incubus seduction).  The existing stop_occupation() call wasn't
sufficient because afternmv is different from occupation.

84f02bd336 intrinsics revamp (trunk only)
Simplify many of the intrinsics macros from
  #define xxx_resistance (Hxxx || Exxx || resists_xxx(&youmonst))
down to
  #define xxx_resistance (Hxxx || Exxx)
by setting or clearing an extra bit in Hxxx during polymorph so that the
resists_xxx() check becomes implicit.

     Unfornately there were lots of places in the code that treat Hxxx
as a timeout number--primarily for Stunned, Confused, and Hallucination;
Stunned happens to be one of the revised macros--rather than as a bit
mask, so this patch needed a lot more changes than originally antipated.

8d5a04a1c0 fix #H2384 - ceiling hiding by poly'd hero (trunk only)
From a bug report, a hero hiding on the
ceiling while poly'd into a piercer or lurker-above could be moved long
distances when a monster attacked his location, because when the attacker
moves into hero's spot, hero's new location is chosen before the attacker
had released its own spot.  If things are crowded, the nearest open space
can be quite far away, including beyond nonpassable walls.  Fix by taking
attacker off the map before choosing hero's destination, so in crowded
conditions they will likely end up trading places.

     This also prevents eels and sharks from moving onto land when the
hero has hidden on the ceiling next to their pool.  They'll miss without
moving into hero's spot, but the hero will become unhidden so they'll be
able to make ordinary water-to-shore attack on their next turn.

     Lastly, when the attacker is a long worm, the spot chosen for hero
might be filled by its tail by the time hero actually moves.  So double
check and possibly re-select target spot after moving a worm's tail.

5bd6ba0d1c magic cancellation and Protection (trunk only)
Magic cancellation comes from some types of worn armor and has a
value of 0 through 3.  A non-zero value guards against some forms of
monster magic attacks (most notably, level drain by vampires and wraiths
and lycanthropy from werecritter bites).  This reduces the effectiveness
of mc a moderate amount (the new values happen to be the same as those
adopted by the Spork variant):
 chance to block various touch effects
  mc  old     new
   1  34.67%  30%
   2  67.33%  60%
   3  98%     90%

    This also makes the Protection intrinsic (strictly speaking, extrinsic)
be the only way to attain an mc factor of 3.  Cloak of protection is the
only way to get mc 3 from a single item.  Otherwise you need an mc 2 item
and a ring of protection (or one of the recently modified quest artifacts).

     Cancellation factor for elven and dwarvish mithril coats and for
robes and oilskin cloaks is reduced from 3 to 2; for elven cloak and
cloak of magic resistance from 3 to 1 (play balance; they're valuable
even without magic cancellation); for dwarven and orcish cloaks and
clocks of invisibility and displacement and for cornuthaum (wizard hat)
from 2 to 1.  Plate mail and crystal plate mail stay at 2.  A variety of
suits which were at 0 are increased to 1; leather jacket and dragon
scales/scale mail stay at 0 (the latter for play balance rather than for
the amount of your body that's covered).

     Having extrinsic protection will increase mc by 1 (unless it's
already 3).  That's obtained by wearing a cloak of protection (where the
increase is redundant), a ring (or two) of protection (even if conferring
a negative AC amount), or wearing the Mitre of Holiness or wielding the
Tsurugi of Muramasa.  Having multiple sources doesn't make the benefit
cumulative; it's just +1.

     Intrinsic protection (bought from priest, gained from prayer, gained
from eating rings of protection while polymorphed into metallivore, or
temporary while spell of protection is active) doesn't increase mc from
armor but does provide minimum mc 1 instead of naked 0 (play balance
again; buying it is too easy to let it increase mc 1 or 2 to 2 or 3).
(Extrinsic protection is a superset; its +1 bonus also increases 0 to 1.)

    TODO: add an amulet of protection so player has another option for
extrinsic protection.

72ca745646 purple worms in wall (trunk only)
From a bug report, a purple worm
could swallow a ghost or xorn and end up inside solid rock.  It took a
bunch of tries to reproduce this, but I eventually did.  (I'm not sure
why it didn't happen every time a worm swallowed a target which was in
rock; the code for positioning an engulfer after it digests a target
always puts the engulfer in the target's former spot.)  After this
patch, worms can still swallow ghosts and xorns, but only when they're
in locations the worm could walk onto.

121b9e9722 small mimic grabbing bug (trunk only)
Noticed while testing the patch for monster ranged attacks when hero
is hidden.  Using #monster while in small mimic form would hide you, as
intended, but the first monster (or last monster?) who hit you hand-to-hand
would be grabbed ("It gets stuck on you.").  Unlike large and giant mimics,
small ones lack such a grab attack so when you eventually returned to
normal form, u.ustuck would remain set and you would end up being stuck
to an arbitrary monster instead of releasing it from your grasp.

d0a7d15023 drain energy attack (trunk only)
During some recent newsgroup discussion, <Someone> posted an entry from
his personal bug list:  energy draining damage from ordinary attacks is
implemented even though there are no monsters with that capability and it
was not implemented for engulf attacks even though energy vortices have
the capability.  This implements energy drain engulf attacks against the
hero and also both modes of energy drain attacks for monsters and poly'd
hero against spellcasting monsters.  Since monsters don't have energy,
they lose access to their special abilities (their spells, that is) for a
few turns, same as a post-3.4.3 change done for anti-magic traps.

61cd699405 monst vs steed tidbit
I came across an old bug report which stated that steeds missed out
on their chance to counterattack if the hero had just taken some action
other than moving.
        [1: monster attacks steed instead of hero ]
        [2: if monster died while attacking, return 1 ]
        if (i & MM_DEF_DIED || u.ux != u.ux0 || u.uy != u.uy0)
                return (0);
        [4: otherwise, steed counterattacks monster ]
Sometime since whatever version the 2001 report was for, but before the
current cvs repository was set up someone addressed this by changing it
to be
        if (i & MM_DEF_DIED || !u.umoved)
                return (0);
but I think that fixed the wrong thing.  I believe that the original code
was attempting to make sure that the steed was still in position to be
able to counterattack.  There's no reason to care about the hero's most
recent action; he had to have done something that caused time to elapse
in order for the other monster to have initiated an attack in the first.
(The new range check is actually redundant; mattackm() also enforces it.)

0ba059f749 Hallucination vs gaze attacks (trunk only)
Suggested by <Someone> in March, 2005 based on newsgroup discussion
at the time:  hallucination protects against touch of death attack by
disrupting how the hero's brain reacts, so why not against gaze attacks
too?  This gives hallucinating hero 75% chance of being unaffected by
gazes.  If unaffected or if the gazer has been cancelled, the gaze will
fail with some feedback.  Previously, all cancelled gazes failed but only
Medusa's gave feedback.

     This will give players another way to defeat Medusa, but since it
isn't foolproof and there are several sure fire ways already, I don't
think it'll hurt play balance there.  It may be useful to avoid getting
repeatedly stunned by Archons though.

8748bf5334 fix #H172 - inconsistent damage calculation for negative AC
Reported last August by <email deleted>:  the code
that decided whether hero poly'd into a pudding would be split when being
hit by an iron weapon always reduced damage by u.uac if armor class is
negative, whereas the normal amount is -rnd(-u.uac).  So player pudding
with good armor always got maximum reduction.  Probably had little actual
effect on game play; puddings can't wear armor so would need to be using
rings and/or spell of protection and/or have eaten rings of protection
while in some previous metallivoric form in order to get good enough AC
for this to matter.

a5640e4bc8 H206 - passive fire damage affecting weapons (trunk only)
<email deleted> reported back on 8/31/06 that elven weapons were not
affected when he poked a fire elemental with them.  This is true, but
moreover, there was no code to have passive fire to affect attackers.
Now erode_obj() supports all the same damage types as rust_dmg(), and added
the connecting code to allow passive fire attacks do something.
There probably should be macros for the damage types used by rust_dmg
and erode_obj, and possibly these functions should be combined, but they
are slightly different and dealing with that requires more thought.

9315307df2 safe_qbuf, short_oname (trunk only)
Change safe_qbuf() so that instead of picking one of three strings
for sprintf() to plug into a prompt string, it actually constructs the
full prompt string itself.  Also pass in the unformatted object and a pair
of formatting functions instead of performing dual formatting in advance.
The actual formatting is done via new routine short_oname() which also
takes an object and a pair of formatting routines plus a target length.
It uses the first routine, typically xname() or doname(), and formats the
object, then if the result is too long it makes some transformations, and
tries again.  If truncating "called foo" and "named bar" down to 12 chars
and omitting "uncursed, rustproof, thoroughly corroded" attributes still
result in a string that's too long, it uses the other formatting routine.
The latter calls one of several jacket routines around simple_typename()
to produce a short result.

     This has been through about four incarnations now and has gotten a
bit less testing each time, but I need to get it in place before I end up
running out of gas and abandoning it.  I've got some changes to shk.c
(where safe_qbuf is needed but not currently used) that now need to be
redone and will come eventually.

365440853b U856 - cockatrice and nurses
One from the way-back machine.  A nurse would hit you-as-cockatrice repeatedly
and never turned to stone.  With this change, nurses will turn to stone (and
also don't heal cockatrices, which seems fair).  I considered giving them
gloves, but that seemed like too much effort.  There are other cases where a
monster "hits" but will not petrify.  However, it doesn't seem like passiveum
detects all the specific ways the monster "hit" you so I left them alone.

f36c9d19fd mon vs mon attack message phrasing
From <Someone>:
  Pet picks up 8 spears.
  Pet wields 8 spears.
  Pet thrusts its spear at Foe.
The routine to handle a monster attacking the hero are already uses "mon
thrusts one of its spears" in this case, so make monster against monster
messages do the same.  Also, it's no longer necessary to save one monster
name before formatting another when using two monster names in the same
message, so switch to the more straightforward usage here.  (The Blind
check is needed in the mhitu case but not in the mhitm one, where it's
redundant because the caller has already verified that both monsters'
locations are visible, but I left it in.)

Huh?  Nothing was visible; nothing became visible (aside from the ']' at my

That's usually handled by the hit and miss routines, but they aren't used

08e9280201 swallowed time (trunk only)
From a bug report, making engulf time longer for high AC
didn't make sense for non-digestion attacks:  taking longer to die from
being digested (high AC lets you last longer there) is much different from
being stuck inside a vortex or elemental and suffering extra buffettings
or whatever.  Calculate swallow time differently for non-digestion than
for digestion.  (The adjustment based around level 25 doesn't make much
sense either, but I left that in.)

     If you survive total digestion via life saving, you get a message
about the monster not liking your taste.  I don't think that's appropriate,
but haven't tried to figure out how to fix it.
